A system includes an accessory for a mobile computing device, the accessory including a body defining an interior configured to secure a mobile computing device, a communications module configured to receive an electronic command to eject a projectile, and a projectile launcher, coupled to the body, configured to eject a projectile in response to the command. The system also includes a projectile disposed in the projectile launcher.

An illuminated feedneck may be utilized in a toy blaster, laser tag gun, airsoft or other toy gun, and the like to illuminate ammunition, such as Gellets, for use in non-daylight hours or indoors. A feedneck may be illuminated through ultraviolet light that may be powered through batteries and/or one or more other forms of power. The illuminated feedneck may charge ammunition through a series of specialty UVA (˜400 nM) wavelength light emitting diodes (LEDs) that safely become illuminated with a long-lasting and bright green glow. The ammunition may be infused to create a glow-in-the dark tracer effect as they are powered and pass through the illuminated feedneck.

A high impact strength lighted nock assembly for an arrow that is activated when the arrow is fired with a bowstring. The lighted nock assembly includes a nock molded from a high impact strength, transparent polymeric material containing at least 10% by weight reinforcing fibers. The nock includes a head configured to engage with the bowstring and a shank configured to couple with a rear end of the arrow. The shank includes a recess extending in a distal end of the shank toward the head. A light assembly including a light emitting device is located in the recess in the shank that is electrically coupled to a battery. A switch is electrically coupled to the light emitting device and the battery that is triggered when the arrow is tired to activate the light emitting device.

A projectile includes a body and a power generator secured to the body. The power generator includes a stator and a ring including at least one magnet and extending radially around and freely rotatable about at least a portion of the stator. A power generator for a projectile is also provided.

One aspect is an illumination assembly including: a first light emitting element; a first counterweight; and at least one of a nock or a connector configured to attach the illumination assembly to a nock, such that the first light emitting element and the first counterweight are positioned symmetrically from each other relative to the nock on opposite sides of the nock. Preferably the first light emitting element is substantially the same mass as the first counterweight. The illumination assembly can include a shaft of an arrow or bolt and/or include an adapter configured to attach to a shaft of an arrow or bolt, such that the first light emitting element and the first counterweight are collinear on a virtual line substantially perpendicular to the central axis of the arrow or bolt, and such that the first light emitting element is positioned off of the central axis of the arrow or bolt and configured to emit light in a rearward direction offset from the central axis of the arrow or bolt.

A projectile is provided for firing from a launcher, including an ogive nose; a cylindrical midsection joined to the nose; and a base curvature shaped as a modified aerospike nozzle. The aerospike base is created using a modified method of characteristics nozzle design process. The aerospike base allows for the efficient expansion of air behind the projectile to recover base pressure and reduce the overall drag of the projectile.

An electronics ordnance delivery system includes an electronics component that is to be delivered into a target. The electronics component is enveloped by a protective housing that assists in the delivery of the electronics component payload. The protective housing is made of an electronically-conductive material such that it can function as an antenna for the transmission of signals by a transmitter component of the electronics component.

A shooting game system using an airsoft gun and an auto tracer control method are provided. To fulfill the above objective, a shooting game system according to an aspect of the present disclosure includes a main body including a muzzle through which a pellet moves, a light-emitting device being mounted in the main body and providing light to the pellet so that the pellet is changed to a fluorescent color in a light-emitting region in the muzzle, a sensor unit configured to detect pulling of a trigger provided on the main body and provide a firing detection signal, a supply unit configured to supply the pellet and compressed gas to the main body, and a control board configured to control the supply unit to provide the pellet and the compressed gas to the main body in response to the firing detection signal, wherein the control board includes an auto tracer controller configured to control the light-emitting device to emit light at a timing when the pellet passes through the light-emitting region in response to the firing detection signal.

A self-glowing solid material comprises a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The material is inducible by flame initiation to self-glow with yellow-to-red colors (577-to-700 nanometer wavelengths). A stealth tracer ammunition comprises a projectile body having a tip and a base, and a solid pellet disposed in the base. The pellet may be made from the above-mentioned self-glowing solid material or another suitable material. The pellet becomes incandescent as a result of being heated when the ammunition is fired. The incandescent pellet emits a glow observable only from behind when the ammunition travels downrange after being fired. An illuminant comprises a bimodal blend of a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The bimodal blend is a blend of smaller-sized fragments and larger-sized pellets. The illuminant is capable of ignition and dispersion in response to ballistic energy to create illumination. An illumination device comprises a body having an interior cavity, the body configured to be launched as a projectile or configured to contain projectiles. An illuminant is disposed in the cavity, the illuminant comprising a bimodal blend of a suitable illuminant material. The illuminant is capable of ignition and dispersion in response to ballistic energy to create illumination.
